QoS design for an enterprise

Let's now apply the concepts discussed in this chapter to design the DiffServ-based QoS architecture for an enterprise. The steps involved in implementing QOS are as follows:

• Define the trust boundary
• Define traffic types and map them into traffic classes
• Determine the number of QoS classes
• Assess the available hardware deployed and the queuing capabilities
• Estimate the bandwidth required for each traffic class
• Map the traffic classes to queues on devices
• Implement the configurations

We will discuss these steps in detail in the subsequent sections.
